A budget and spatial representation of Phosphorus in the central Arizona-Phoenix area

Phosphorus is a limited resource and a critical element in biogeochemistry. The raster datasets included here were created to show the spatial distribution of phosphorus stocks, accumulation, and throughput in the Central Arizona Phoenix Long Term Ecological Research study area. These rasters were created as the products of a phosphorus budget compiled within the CAP-LTER study area and are intended to be used by researchers studying biogeochemical cycles and sustainability. The raster of phosphorus stocks show the distribution of both abiotic and biotic phosphorus pools in the environment, which generally have long residence in the urban ecosystem. The accumulation and throughput raster show the likely areas where phosphorus will aggregate (inputs-outputs) over time and throughput shows areas with the highest inputs plus outputs of P. In addition to our final products we also include rasters used as variables to calculate the raw stocks, accumulation, and throughput rasters.

磷是一种有限资源，同时也是生态系统生物地球化学循环中的关键元素。本次提供的栅格（raster）数据集，旨在展示亚利桑那州凤凰城中央长期生态研究（Central Arizona Phoenix Long Term Ecological Research, CAP-LTER）研究区内磷储量、累积量与通量的空间分布格局。此类栅格为基于CAP-LTER研究区磷收支核算生成的成果，可供研究生物地球化学循环与生态可持续性的科研人员使用。磷储量栅格可呈现环境中非生物与生物磷库的分布特征，这类磷库在城市生态系统中通常具备较长的驻留时间。磷累积与通量栅格则可显示随时间推移磷可能发生聚集（输入-输出过程）的区域，其中通量指代磷输入与输出总量最高的区域。除上述最终成果栅格外，本数据集还包含用于计算原始储量、累积量与通量栅格的变量栅格。如需了解各图层的具体计算方法，请参阅：http://www.esajournals.org/doi/pdf/10.1890/11-0865.1，该文献刊载于《Ecological Applications》2012年第22卷第2期，第705至721页，版权归2012年美国生态学会所有。论文作者为Metson, G、R Hale、D Iwaniec、E Cook、J Corman、C Galletti与D Childers，论文标题为"Phosphorus in Phoenix: a budget and spatial representation of phosphorus in an urban ecosystem"，发表信息同前。
